Depending on results elsewhere, Dortmund could find themselves bottom of the standings at the start of play on Sunday. BVB's five-match losing league run stands in stark contrast to the form of Gladbach, who made it a club record 18 games unbeaten in all competitions after Thursday's UEFA Europa League win in Limassol.
Assuming Roman Weidenfeller and ex-Foal (right) are fully recovered from an untimely stomach virus, Jürgen Klopp looks set to name the same starting XI for the third game running. BVB nevertheless have plenty of options on the bench including Kevin Großkreutz, Ilkay Gündogan, Ciro Immobile and Adrian Ramos.
Lucien Favre rang the changes in Cyprus on Thursday night, but is expected to revert to his favoured starting line-up at Signal Iduna Park. Martin Stranzl, Andre Hahn, Patrick Herrmann and Raffael will almost certainly start, while leading goalscorer (left) is fit again after missing out in Limassol with a thigh strain.
With nine goals in all competitions, has been one of BVB's more consistent performers in 2014/15. The Gabon international grabbed a cool assist in last Saturday's 2-1 defeat at FC Bayern München and appears to have become Klopp's go-to guy in the lone striker department.
Patrick Herrmann has hit top form of late, scoring two and laying on another in last weekend's 3-1 win over TSG 1899 Hoffenheim. The 23-year-old winger has the pace to trouble even the most disciplined of Bundesliga full-backs and, with three goals and one assist in five league outings, has the end product to boot.
, BVB midfielder: "We have to prove after a good Champions League game we can get points in the league too."
Lucien Favre, Gladbach head coach: "Dortmund still have the quality [to compete]. They've proved that in the Champions League."
BVB remain without a league win since September, despite boasting an unblemished record in this season's UEFA Champions League after four games. Third-in-the-table Gladbach, meanwhile, haven't lost since last May's 3-1 defeat at VfL Wolfsburg.
Gladbach did the double over Dortmund last season after recording their first league win at Signal Iduna Park in over a decade on 15 March. Prior to that, BVB had won eight of their previous nine home games with the Foals, drawing the other 1-1 in January 2005.
